I'm on SF4, which is a trifle elderly, but it does everything I need (erm... almost... !!)This evening I've been transferring an old cassette onto CD - Sound Forge made light work of it. My trick is to slightly under record, then sort out the volume to 0dB on each channel afterwards - it avoids any 'clipping' (digital recording is so unforgiving!).
Anyway, that CD should just about have finished 'burning', now...
